In this contribution we present a domain decomposition framework for the multiscale analysis of softening materials. In particular we focus on the finite element tearing and interconnecting (FETI) technique implemented in ...

In this contribution we describe a methodology for the study of softening brittle materials at different scales of observation. The goal is to account for a higher resolution at those areas that undergo the non-linear ...

A computational homogenization procedure for cohesive and adhesive crack modeling of materials with a heterogeneous microstructure has been recently presented in Computer Methods in Applied Mechanics and Engineering (2010, ...

Understanding physical phenomena of heterogeneous materials is an ongoing active research field in the structural design of buildings and roads. The failure analysis of quasi-brittle materials such as concrete is a particular ...

In this study a FETI: Finite Element Tearing and Interconnecting [1] technique is adopted and exploited for the efficient and accurate modeling of softening materials such as concrete and rock. A fie scale analysis in which ...

The existence of a representative volume element (RVE) for a class of quasi-brittle materials having a random heterogeneous microstructure in tensile, shear and mixed mode loading is demonstrated by deriving traction–separation ...

In this contribution, dual and primal domain decomposition techniques
are studied for the multiscale analysis of failure in quasi-brittle materials. The multiscale strategy essentially consists in decomposing the structure ...

In this contribution we present a multiscale framework for the analysis of brittle materials based on domain decomposition approaches. In particular, the FETI (Finite Element Tearing and Interconnecting) [1] method is ...

This paper presents an assessment of a two-scale framework for the study of softening materials such as concrete. The procedure is based on a hierarchical Finite Element (FE) scheme in which computations are performed both ...

The multiscale framework presented in [1, 2] is assessed in this contribution for a study of random heterogeneous materials. Results are compared to direct numerical simulations (DNS) and the sensitivity to user-defined ...

In this contribution we describe a methodology for the multiscale analysis of heterogeneous quasi-brittle materials. The algorithm is based on the finite element tearing and interconnecting FETI [1] method cast in a ...

The concept of the representative volume element (RVE) for softening materials is revised in this contribution. It is demonstrated by means of numerical simulations that there exists a sample which is statistically ...

The concept of the Representative Volume Element (RVE) is analysed in the present paper. For elastic materials, one can determine the size of the RVE. However, for other applications, such as the case of softening materials, ...

We focus on the analysis of fracture in quasi-brittle materials by exploiting the potential of domain decomposition techniques. More specifically, we restrict our attention to the FETI (Finite Element Tearing and ...
